VALVE FOR SWIMMING-BAGS.

SPECIFICATION forming part of Letters Patent No. 760,948, dated May 24, 1904. Application filed December 2, 1901. Serial No. 84,419.- (No model.)

To all whom it may concern.-

Be it known that I, HACHIGZA. AYvAD,a citizen of the United States of America, and a resident of Hoboken, in the county of Hudson and State of New J ersey,have invented certain new and useful Improvements in Valves for Swimming-Bags, of which the following is a specification.

The object of my invention is to provide an inexpensive and efiicient valve for the swimming-bags or life-preservers such as patented to me in my United States Letters Patent No. 67 3,672, dated May 7, 1901.

This valve .consists of two parts, an apertured body and a flexible flattened valve-tube. The apertured body is the mouthpiece of the valve and is of metal or other stifl material, so that the hole through it will not be closed when it is seized between the lips. The valvetube is of flexible material, the walls of which can be readily flattened against each other to close the tube. This portion is of cloth or some material which saturates readily, so that when saturated and the walls are in contact the walls will be sealed to each other by the capillary action of the water. One end of the valve-tube is connected to the apertured body in a suitable manner.

- In the accompanying sheet of drawings, which forms a part of this specification, Figure 1 is an'enlarged view of the portion of the swimming-bag to which the valve is attached, the part of the valve within the bag being shown in dotted lines. Fig. 2 is a similar view of the same portion of theswimming-bag, showing the bag laid open and the collar by which the valve -tube is bound to the apertured body in section, so that the Valve-tube can be shown entirely in full lines.- Fig. 3 is a view of the entire swimming-bag with the valve attached.

The apertured body is ametal tube a about three-sixteenths of an inch in diameter and of muslinabout an inch and a quarter square. The piece is folded along the middle and the vmeeting edges parallel to the fold are sewed together with a double row of stitches.

In manufacturing the swimming-bag I do not make up the valve complete before connecting it, but make it in connection with the manufacture of the bag. The flexible valvetube or cloth portion is inserted in its place in the bag before sewing on the binding of the bag. Then the binding is sewed on, commencing at the valve-tube. The first stitch through the binding is also taken through the cloth tube close to its fold. The binding completely encircles the bag except at the valve and ends at the side of the valve-tube opposite the fold, and the last stitch through the binding is also through the side of the valvetube. Both sides of the flattened valve-tube are thus secured to the bag. The valve-tube is thereby held in direct contact with the bag, andsince the bag when in use is in water the valve-tube will be kept thoroughly wet by capillary action through the walls of the bag and of the tube, a moistened condition of the valve-tube being necessary to make it an eifectual seal to the air. The tubular portion on the apertured body or metal mouthpiece is then inserted into the valve-tube and the flexible metal strip is wrapped around the portion of the valve-tube which lies over the metal tube and binds the two together.

The bag is only used while wet, and the water renders the cloth portions impervious to air.

The term flattened where used doesnot mean that the valve-tube is necessarily flat when made, but that although the same is of a tubular nature it is flattened more or less when it is in using condition, it only being necessary to wet it to place it in such condition. 7

By saturating the bag the porous valvetube is also saturated. The porous nature of the valve-tube enables it to become well saturated with water, and the opposite saturated walls thereof are caused to cohere by capillary action. To' be more specific, the water to supply the meeting faces of the valve-tube is by the capillary action drawn from the pores of the muslinior equivalent material, so that the walls become sealed and maintain the valve closed after air has been blown into the mouthpiece to inflate the bag. Owing to the yielding nature of the bag, the same may be compressed by the fingers to squeeze or compress the valve-tube.

What I claim as new, and desire to secure by Letters Patent of the United States, is

1. A valve consisting of a mouthpiece and a collapsible porous valve-tube of woven fabric, in combination with a bag the walls of which can be compressed against the walls of the valve-tube, substantially as described.

2. A valve consisting of a mouthpiece and a collapsible porous valve-tube of woven fabric, in combination with a bag of woven fabric, the walls of which are in contact with the walls of the valve-tube, substantially as described.

3. A valve consisting of a mouthpiece and a collapsible porous valve-tube of woven fabric, in combination with a bag of woven fabric, the walls of which are in contact with the walls of the valve-tube, and can be compressed against the walls of the valve-tube, substantially as described.

4:. In combination with an inflatable and compressible swimming-bag having a binding extending around its edge, a valve consisting of a mouthpiece, exposed at the surface of the bag, and a flexible, compressible valvetube of Woven fabric attached to the mouthpiece and extending therefrom to between the compressible wall of the bag, the ends of the bag-binding being stitched to the edges of the valve-tube, substantially as described.

Signed by me in New York city, (borough of Manhattan, New York,) this 27th day of November, 1901.
